Serena 'can complete 2014 Grand Slam'

Serena Williams can become the first woman to complete a calendar Grand Slam since 1988, according to her coach.

Williams, 32, held all four grand slam titles at the same time after triumphing at the Australian Open in 2003, though no female player has won all four in the same calendar year since Steffi Graf 26 years ago.

The world No.1 enjoyed an exceptional 2013, winning the French Open and the US Open with just four defeats all year. However two of those came in the other two grand slams, as she fell to compatriot Sloane Stephens in the quarter-finals at Melbourne and lost to Sabine Lisicki in the fourth round at Wimbledon.

The American has already started 2014 in fine form, storming past Maria Sharapova and Victoria Azarenka on her way to winning the Brisbane International without dropping a set.

"With Serena, everything is possible," Patrick Mouratoglou told BBC Sport on the eve of the draw for the Australian Open in Melbourne.

"Look at the level she plays at at the moment. She's beaten all the top players many times, so you can aim that high.

"Of course it would be exceptional because it's crazy to do that. It's happened just a few times in the history of tennis - but she can do it and the goal is to do the best possible in all four grand slams. So why not?"
